Prefix Problems

I'm currently setting up a prison section on a server I work with, and I'm having issues with prefixes. First I made ranks A-Z and such, I deleted the "Default" rank and set it so that A was the default, and when I tried to do /mangaddv A prefix &7[&aA&7], it didn't work. I set myself to the A rank and when I talked no prefix showed up, it just gave my name. If you want to see any config things just ask, I don't know what is causing this problem. Thanks.

If this is your plugin that you wrote, post the code here. If not, click report and ask this to be moved to general help.

Are there any errors in the console? Any feedback messages? Also, what do you mean by "didn't work"? Can you be more descriptive?

 

Sorry, this problem is solved.
